The market on whether the next Claude Opus model will release by July 31, 2026, saw its YES contract price fall sharply by 18.5 percentage points in the past 24 hours, dropping from 93.0% to 74.5%. This shift reflects a significant pullback in confidence about the release timing.
Despite this marked decrease in the market’s implied probability, whale activity diverged from the price trend. Large traders increased their exposure to YES positions, betting $0 net into the outcome even as the price declined. This flow-price divergence suggests that while the broader market trimmed expectations, whales maintained or added to their conviction on a July 31 release.
Trading volume over the last day was moderate, totaling $19K on Polymarket.
This divergence between whale flow and price movement highlights a complex dynamic where retail or smaller traders appear to be reducing their exposure, while whales hold steady or increase theirs. The market’s direction remains uncertain but closely watched given this split.
